An optimum Hamiltonian for non-Hermitian quantum evolution and the complex Bloch sphere | Alexander I Nesterov
; | Date: |
28 Jun 2008 | Abstract: | For a quantum system governed by a non-Hermitian Hamiltonian, we studied the
problem of obtaining an optimum Hamiltonian that generates nonunitary
transformations of a given initial state into a certain final state in the
smallest time $ au$. The analysis is based on the relationship between the
states of the two-dimensional subspace of the Hilbert space spanned by the
initial and final states and the points of the two-dimensional complex Bloch
sphere. | Source: | arXiv, 0806.4646 | Services: | Forum | Review | PDF | Favorites |
